Spark Plug replace/change DIY
#122
Last noob question - I swear I have the 3 fronts replaced, and wont have time to do the back 3 before i leave for a 400 mile road trip. I'm assuming nothing bad will happen other than , wont perform as good as 6 new plugs. any potential codes for exhaust issues ??
#123
if you only torqued the plugs about 1/4-1/3 of turn after it was seated then no need to lossen them.
#125
what makes you think you overtightened them? did they make creaking noise?
were you holding on the end of a ratchet and pulling wildly?
or hand directly on top of ratchet and tighten gently?
should have mentioned that trick before- = about 10 lbs
When they get to a point where it feels naturally tight- plus a little more- thats right
iirc its 13-16 range allowed
dont loosen and set that as torque
loosen, and bring UP to spec- that holds them in tight..like tuning guitar strings
no worry on the back 3 if they dont get done- no codes, maybe a percent less economy and smoothness will be off

totald- what are you defining a long reach socket as?
I have a few that fit the TL, a standard rubber insert type, is that long reach- in your opinion? or some trick tool I dont know about

when the timing belt is in place and doing its job- there is no concern of valves contacting pistons- all works together and they are open and closed at the correct `time`
If the `timing` belt breaks, the exhaust valves that are open will make contact with the pistons when it hits top dead center, bends valve stem
they would pretty much have to be the wrong plug- with too long a reach- to hit the piston in normal operation

oh I see
For me--not having one of those,,I like the 3 and 6 inch extensions for lowering the tool in pieces where needed

I did have one plug that caused some issues coming out - I thought the threads were stripped and started sweating bullets. It was just really rusted ? And at the bottom of the ceramic there was some black oil. Was this probably a fouled plug ? Or EGR or PCV need to be cleaned ? Worn Ring ?
#131
a few of them often feel stuck= its surface rust, corrosion bonding, and the fact honda didnt use anti sieze on the plugs at install
dirt and grime get in there on top of the plugs and heats, spreads everywhere...
as long as the working part of the plug looked good- its tip was tannish grey, then all is well with your system
if more than 75kmiles its ready for egr port cleaning
pcv just use carb cleaner or deep creep/seafoam to clean the valve

They work very well on my V8 truck but I would not use them on a japanese engine tho. Im using the E3's right now and they have been great but most sick with the NGK stuff
#135
1. Thanks for the feedbacks regarding Bosch, I'd better not use them.
2. Have been struggling with the passenger rear plug 30 minutes. Lost the bolt on PS line, falling down the engine bay and disappeared, removed 4 bolts of the crossbar on "strut bowl" only to realize that the bar still unmovably attachs to the firewall probably with rivets, don't see any bolts.
The one who designed that $%&^%*&^ should be shot.

should have checked this thread before i changed my plugs.. i went to napa auto parts and when i asked for plugs, they automatically gave me the ngk g-power plugs.. anyone using these? i shouldve known to ask for iridiums, but ive been messing with my mustang so long that i was used to autolite cheapo plugs.. lol
#139
g power are NOT the correct plugs- take them back
we use ngk platinum (came stock) but more use gen3s plug Iridium or Iridium IX
which are fine in our engine
not any other designation or multi prong nonsense
the right plugs are about 8 bucks each,,anything else will cause problems

If your super cheap or just need a quick replacement, I can vouch for the Autolite double platinum plugs. I ran them for about 70k miles, and switched them out for NGK Iridiums. They looked like they could run for another 70k, and I experienced no change when I installed the Iridiums.
Of course, the safe bet is the Iridiums, but I just thought I would share my experience.

and that whole time you were experiencing lessened performance
NGK or denso (cost more and last less miles)

did you use a live scanner to see what your actual performance was?

I tightened my plugs with a torque wrench @14ft-lbs when the engine was HOT, so I went back to reinstall them when the engine was cold. The first two didn't really seem to be overtightened or anything, so I left the rest.
However, my plugs had a black soot on them. From googling, it seems that this is caused by a rich A/F ratio? My mpg is pretty good (~30hw, 20city). Should I change the O2 sensors?
#147
K7-- seafoam it and recheck plugs
just color or real buildup on them?
correct ngk plugs?
DIDNT SEEM!!!! they are torque spec cold,,, or they are not~ not seems!
loose plugs from HOT install may have caused leak and problems
ck them cold at 14, not more not less

Just did mine for the first time. The idiot before me, whether it was the dealer or previous owner, had installed the wrong plugs. I guess that could explain the weird idle; it's smooth as can be now.
I ended up using only (2) 3" extensions, which was a little shorter than (1) 6" extension. Make sure your remove the bracket that holds the power steering line in place and the cruise control motor for the rear plugs. That made my life much easier. I would say it only took me 30 minutes.

scubasteve (diver signal for question-u OK?)
the cusco or other brands upper strut crossbar does not replace the stock one!
It supplements it, and goes only between the towers
the stock unit is more for locating the body/firewall to the shock towers/fenders
and reduces flex up top
also great is cusco lower cross bar, goes across frame where the rails split wide to create the trans/engine cradle
Putting a brace there stops a lot of frame flex, and holds the lower shock mounts/steering in place during turn loading
Makes lane changes at speed- flat!

Ok guys so I have the Seafoam running through my gas tank as I type this. And will go out to get the spark plugs tomorrow.
now the general consensus is that NGK iridium spark plugs are best. But what if I get the Bosch Iridium plugs?
I read that it might misfire but if i do a ECU reset might that take care of the problem?

There is a couple of iridium IX, which model correct one for our car?
Is it NGK (2477) ZFR5FIX-11 Iridium IX Spark Plug?
I found it on amazon $6.25 a piece(over $25 free shipping). It's the best price ever seen on line.
http://www.amazon.com/NGK-ZFR5FIX-11...=cm_cr_pr_pb_t
I think it cheaper than any auto shop or ebay if the model No. is correct.

Changed the plugs two days ago, took me about 45 minutes to get it done. Thanks for the great DIY info. I also changed the cabin filter, man was damn filter filthy. AC blows a lot better and much cooler. I'm loving this site.

And does anybody know if there is a difference between the spark plugs for the TL-P and TL-S?
I went to O'Reillys and he asked if it was a regular, or type S. I said just give me a type S (even though i have a TL-P) because I didnt think there would be a difference and thought the S ones would spark stronger or something.
